History:

Peanut butter cake recipes have been around for quite some time, especially in the United States, where peanut butter has been a staple since the early 1900s. The addition of peanut butter to cakes became particularly popular in the mid-20th century. Originally, peanut butter was used as a topping for cakes or incorporated into frostings. Over time, bakers began creating peanut butter-flavored cakes themselves, pairing them with complementary flavors like chocolate and vanilla.

The sheet cake form of this dessert became a favorite because it’s easy to make in large batches, perfect for serving crowds at family gatherings, potlucks, and celebrations. It’s a no-fuss way to enjoy a delicious cake without the need for intricate decorating skills.

Ingredients:

For the Cake:

2 cups all-purpose flour
1 teaspoon baking soda
1/2 teaspoon salt
1/2 cup unsalted butter, softened
1 cup peanut butter (creamy or chunky)
1 cup granulated sugar
1 cup packed brown sugar
3 large eggs
1 teaspoon vanilla extract
1 cup buttermilk (or milk if unavailable)
1/2 cup boiling water
1/2 cup sour cream (optional for extra moistness)

For the Peanut Butter Frosting:

1/2 cup unsalted butter, softened
1 cup peanut butter (creamy or chunky)
4 cups powdered sugar
2-4 tablespoons milk (or heavy cream for extra richness)
1 teaspoon vanilla extract
Pinch of salt (optional)

Optional Garnish:

Chopped peanuts or mini chocolate chips for sprinkling

Method/Instructions:

For the Cake:

Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan, or line it with parchment paper for easy removal.
Combine Dry Ingredients: In a medium-sized bowl, whisk together the flour, baking soda, and salt. Set aside.
Cream Butter and Peanut Butter: In a large bowl, cream together the softened butter and peanut butter using an electric mixer on medium speed. Add both the granulated sugar and brown sugar, and continue beating until light and fluffy (about 3-4 minutes).
Add Eggs and Vanilla: Beat in the eggs, one at a time, ensuring each one is fully incorporated before adding the next. Stir in the vanilla extract.
Alternate Adding Wet and Dry Ingredients: With the mixer on low speed, alternate adding the dry ingredients and the buttermilk to the butter mixture, beginning and ending with the dry ingredients. Mix until just combined.
Add Boiling Water: Pour in the boiling water and sour cream (if using), mixing carefully until the batter is smooth. The batter will be thin, which is normal.
Bake the Cake: Pour the batter into the prepared baking pan and spread it evenly. Bake for 30-35 minutes, or until a toothpick inserted into the center of the cake comes out clean.
Cool the Cake: Allow the cake to cool in the pan on a wire rack for about 10-15 minutes. Once slightly cooled, remove from the pan (if using parchment) and let it cool completely before frosting.

For the Peanut Butter Frosting:

Cream Butter and Peanut Butter: In a large bowl, use an electric mixer to beat together the softened butter and peanut butter until creamy and smooth.
Add Powdered Sugar: Gradually add the powdered sugar, one cup at a time, mixing on low speed to prevent a sugar cloud. Once all the powdered sugar is added, increase the speed to medium and beat until fluffy.
Add Milk and Vanilla: Add the milk, starting with 2 tablespoons, and vanilla extract. Beat until smooth. Add more milk if needed to reach a spreadable consistency.
Frost the Cake: Once the cake is completely cooled, spread the peanut butter frosting generously over the top, smoothing it into an even layer with a spatula.
Optional Garnish: Garnish the top of the cake with chopped peanuts or mini chocolate chips for a little extra texture and flair.

Method Tips:

For a more intense peanut flavor, use chunky peanut butter in both the cake and the frosting.
Make it extra moist by using sour cream or substituting part of the butter with oil. This will make the cake even richer and more tender.
For a deeper chocolate flavor, add some cocoa powder or melted chocolate to the frosting, turning it into a “Peanut Butter and Chocolate” version.
